Inertia 2: Definitive Edition

Inertia 2: Definitive Edition is the next chapter from the creator of Inertia - a first-person platformer built entirely around fluid, refined movement mechanics.

Nine years on, the foundation that made Inertia resonate with players is back - smoother, deeper, and complete from day one.

Move. Inertia 2: Definitive Edition is built on a refined and evolved movement system - wall-runs, platforming, and fluid traversal that rewards mastery without punishing newcomers. Whether you're here to play casually or chase world records, the movement adapts to your playstyle.

Create. Build your own levels with a full in-game level creator. Place every element and geometry feature found in the official levels - jump pads, wall-runs, elevators, rising platforms, horizontal movement platforms, and material-editable geometry across a curated set of surfaces. No external tools, no complexity - just build and play.

Compete. Steam Leaderboards with anti-cheat measures put your times on the board from day one. Every official level; every community level - compete, compare, and chase the top spot. The speedrun community has a home here from launch.

Workshop. Share your levels with the world through full Steam Workshop integration. Browse, subscribe, and play community-created levels without leaving the game. The Workshop is live from Early Access - meaning the community is already building by the time 1.0 arrives.

The Definitive Edition difference. The original Inertia earned its community over time - Workshop support, leaderboards, and the level creator all arrived at 1.0. Inertia 2: Definitive Edition launches with all of it. Every feature, from day one.
